Bruxism is the techinical term for grinding and clenching of the teeth that may cause facial pain. People who grind and clench their teeth, called bruxers, unintentionally bite down too hard at times, such as in their sleep. People usually aren't diagnosed with bruxism until tooth damage is already done, as people often don't realize they have the habit. About one in three people suffer from bruxism, which can often be easily treated by our dental office.
